Description
Thanks to its excellent particle identification and momentum
measurement capabilities, the ALICE detector allows for the identification
of deuterons, tritons, $\rm ^{3}{He}$ and $\rm ^{4}{He}$ and and their
corresponding antinuclei. This is achieved via their specific energy
loss in the Time Projection Chamber and the velocity measurement by the
Time-Of-Flight detector. Moreover, thanks to the Inner Tracking System capability
to separate primary from secondary vertices, it is possible to identify
(anti-)hypertritons exploiting their mesonic decay
($\rm ^{3}_{\Lambda}{H}$ $\rightarrow$ $^{3}\rm{He}$ + $\pi^-$).
Results on the production yields of light nuclei and anti-nuclei in Pb--Pb,
pp and p--Pb will be presented, together with the measurement of
hypertriton production rates in Pb--Pb. The measurement of the hypertriton
lifetime will also be shown.
The experimental results will be compared with the predictions of both thermal
(statistical) and coalescence models.
